floor lamp torchiere replacement?

I recently broke the glass shade part of a tall floor lamp (the torchiere part). The lamp still works so I don’t want to buy a whole new one.

Do you know where I can get a replacement glass shade for it? Especially if I am looking for a plain, standard glass one (not an antique or expensive Tiffany style one)?

Are most replacements standard in size, sort of like a one size fits all?

Thanks.
